Dinsmore Bridge, Transportation bridge in Richmond, Canada

Dinsmore Bridge is a low-level concrete bridge over the Middle Arm of the Fraser River in Richmond, British Columbia. It carries two lanes of traffic on concrete pillars and has a pedestrian sidewalk on its west side. The posted clearance is 4.3 metres.

The bridge opened in 1969 as part of a larger infrastructure project to connect Vancouver International Airport. It was built to link key transportation points in the region.

The bridge and the island it crosses take their name from the Goodmurphy cannery, which opened in 1894 and was incorporated the next year as the Dinsmore Island Canning Co. by John Dinsmore, M.B. Wilkinson, W.D. Goodmurphy and Caleb Goodmurphy. The cannery's presence renamed the site Dinsmore Island; BC Packers later acquired the plant, which was demolished in 1913.

The bridge is a low-level, two-lane crossing with a pedestrian sidewalk on its west side; cyclists share the roadway with vehicles. The posted clearance is 4.3 metres (14.1 ft). Traffic from Russ Baker Way merges into one lane to cross, so expect queues at rush hour. It gives the most direct access to Richmond Hospital and the WorkSafeBC headquarters.

As a federally owned structure, the bridge requires all signage to display information in both English and French in accordance with Canadian language policy. This bilingual requirement is notably visible throughout the crossing.
